SPECIFICATION forming part of Letters Patent No. 332,057, dated December 8, 1885.

Application filed September 2, 1885. Serial No. 175,974.

To all whom it may concern:

Be it known that I, HURVEY COOPER, a citi- Zen of the United States, and a resident of \Vestfieldfln the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in W'aterWVheels; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and "use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a side elevation of a waterwheel embodying; my improvements. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a vertical transverse sectional view taken on the line 0000 in Fig. 1; and Fig. 4 is a detail view, in perspective, of one of the buckets of my improved waterwheel.

The same letters refer to the same parts in all the figures.

This invention relates to hydraulic motors or water-wheels of that class which consist of a wheel or disk the rim or periphery of which is provided with a series of buckets; and it has for its object to provide a water-wheel of this class which shall possess superior advantages in point of simplicity, durability, and general eiiiciency, and in which certain objections which are common to this class of water-wheels as ordinarily constructed shall be done away with.

\Vith these ends in view the invention consists in the improved construction and arrangement of the component parts of the said water-wheel, which will be hereinafter more fully shown and described.

In the drawings hereto annexed, A designates the body of my improved water-wheel, which may be composed of a single solid piece or disk, or it. may, as in the drawings, consist of a suitable rim or flange, 13, connected by the spokes G G with the hub D. The rim or periphery of the wheel is provided with an annular groove or recess, E, around which is placed a band or tire, F, which may be constructed of brass or of any other suitable metal.

G G designate the buckets of the wheel, which are constructed of heavy sheet metal by first cutting a plate of the same to the proper size and shape, and then bending the (No model.)

ends of the same up at right angles, so as to form wings or flanges H H, the lower edges of which are cut off at an acute angle to the front. side or body of the bucket. These buckets are brazed or otherwise suitably secured to the rim or tire of the wheel suitable distances apart. The rim or tire F is provided at each one of the buckets with a perforation, I, communicating with the annular groove or recess E.

\Vhen my improved water-wheel is in operation and revolves at a high rate of speed, the openings I I form vents, which will perniit the water readily to enter each one of the buckets. YVithout these vents the suction created by the rapid revolution of the wheel will prevent the water from filling the buckets, thus rendering the operation defective, and detracting from the power which should be derived from my improved water-motor. The discharge from the buckets will, for the same reason, be more readily effected, and there will, therefore, be no waste of power.

My improved hydraulic motor will usually be used as an overshot wheel, although the principle herein described may also, with proper modifications, be applied to water-- wheels of the class known as undershot.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a water-wheel, the combination of a wheel or disk having a peripheral groove or recess, a tire fitted around the said wheel or disk and provided with suitably-constructed buckets, and perforations in the said tire registering with the said buckets and connecting the same with the annular groove or recess, substantially as and for the purpose herein set forth.

2. In a water-wheel, the combination ofan annularly-grooved wheel or disk with a rim or tire having perforations communicating with the said annular groove, and a series of buckets secured to said rim, substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

HURVEY COOPER.
